<td><p>Radiocarbon dating was created in the 1940s by Willard F. Libby</br> at the University of Chicago.  It is used in many different fields as an</br> accurate way to date artifacts and ecofacts.
Radiocarbon dating </br> takes advantage of something known as half-life.  Half-life (as defined</br> in the Merriam-Webster dictionary) is “the time required for half of the </br>atoms of a radioactive substance to become disintegrated.”  If you can </br> determine how much carbon 14 is left in an organism, you can determine the</br> age through half-life.
